geneos management program

⚠️ Please now use cordial instead of this repo
I have now been able to move this project into the official ITRS-Group repo and given is a new name as it contains mix of Geneos related tools, libraries and packages. Please head over to https://github.com/ITRS-Group/cordial for the updated repo.

⚠️ Breaking Changes v1.1+

v1.1 is an almost complete rewrite of the geneos program and there will be breaking changes. Most of these will be command line flags, options, configuration file contents and support for old, obscure options. The trigger for many of these changes is the move to use well-known and mature packages for configuration handling (viper) and command line options (cobra) as well as the untangling of internal spaghetti code which made calls in and out of multiple layers of functionality. I have attempted to update this documentation to match the new functionality and to also highlight known changes for you, but it is highly probable that some things have been missed.

The geneos program will help you manage your Geneos environment on Linux.

Basic Features

• Initialise a new installation in one command
• Adopt an existing installation that uses older tools
• Manage a group of servers with a single command
• Manage certificates for TLS connectivity between Geneos components
• Configure the environment of components without editing files
• Download and install Geneos software, update components
• Simple bootstrapping of Self-Announcing Netprobes

Aims

• Keep it simple through the Principle of least astonishment
• Make your life easier; at least the part managing Geneos
• Help you use other automation tools with Geneos

Concepts & Terminology

Many of the terms used in this documentation and in the program itself assumes some familiarity with the Geneos suite of products and this is not always the case, so here are some starting points. Many of the key terms have been inherited from earlier systems.

The specific types supported by this program are details in Component Types below.

Geneos

Geneos is a suite of software products from ITRS that provide real-time visibility of I.T. infrastructure and trading environments. It uses a three-tier architecture to collect, process and present enriched data to administrators.

Components

A component is a type of software package and associated data. Each component will typically be a software package from one of the three-tiers mentioned above but can also be a derivative, e.g. a Self-Announcing Netprobe is a component type that abstracts the special configuration of either a vanilla Netprobe or, for example, the Fix Analyser Netprobe.

Instances

An instance is an independent copy of a component with a working directory, configuration and other persistent files. Instances share read-only package directories for the binaries and other files from the distribution for the specific version being used.

Hosts

Hosts are the locations that components are installed and instantiated. There is always a localhost.

Getting Started

Download the binary

You can download a pre-built binary version (for Linux on amd64 only) from this link or like this:

curl -OL https://github.com/pgalbavy/geneos/releases/latest/download/geneos
chmod 555 geneos
sudo mv geneos /usr/local/bin/

Build from source

To build from source you have Go 1.17+ installed:

One line installation

go install wonderland.org/geneos/cmd/geneos@latest

Make sure that the geneos program is in your normal PATH - or that $HOME/go/bin is if you used the method above - to make things simpler.

Download from github and build manually

Make sure you do not have an existing file or directory called geneos and then:

github clone https://github.com/pgalbavy/geneos.git
cd geneos/cmd/geneos
go build
sudo mv geneos /usr/local/bin

Adopting An Existing Installation

If you have an existing Geneos installation that you manage with the command like gatewayctl/netprobectl/etc. then you can use geneos to manage those once you have set the path to the Geneos installation.

⚠️ WARNING

geneos ignores any changes to the global .rc files in your existing installation. You must check and adjust individual instance settings to duplicate settings. This can sometimes be very simple, for example if your netprobectl.rc files contains a line that sets JAVA_HOME then you can set this across all the Netprobes using geneos set netprobe -e JAVA_HOME=/path/to/java. More complex changes, such as library paths, will need careful consideration

You can use the environment variable ITRS_HOME pointing to the top-level directory of your installation or set the location in the (user or global) configuration file:

geneos set user geneos=/path/to/install

This is the directory is where the packages and gateway (etc.) directories live. If you do not have an existing installation that follows this pattern then you can create a fresh layout further below.

Once you have set your directory you check your installation with some basic commands:

geneos ls     # list instances
geneos ps     # show their running status
geneos show   # show the default configuration values

None of these commands should have any side-effects but others will. These may not only start or stop processes but may also convert configuration files to JSON format without prompting. Old .rc files are backed-up with a .rc.orig extension and can be restored using the revert command.

New Installation

New installations are set-up through the init sub-command. In it's most basic form it will create the minimal directory hierarchy and your user-specific geneos.json file containing the path to the top-level directory that it initialised. The top-level directory, if not given on the command line, defaults to a directory geneos in your home directory unless the last part of your home directory is itself geneos, e.g. if your home directory is /home/example then the Geneos directory becomes /home/example/geneos but if it is /opt/geneos then that is used directly.

If the directory you are using is not empty then you must supply a -F flag for force using this directory.

Demo Gateway

You can set-up a Demo environment like this:

geneos init -D

If authentication is required to download the software archives then use these extra options:

geneos init -D -u [email protected]

or

export [email protected]
export ITRS_DOWNLOAD_PASSWORD=mysecret
geneos init -D

Here you should replace the email address with your own and the command will prompt you for your password. These are the login details you should have for the ITRS Resources website.

The above command will create a directory structure, download software and configure a Gateway in 'Demo' mode plus a single Self-Announcing Netprobe and Webserver for dashboards. However, no further configuration is done, that's up to you!

Behind the scenes the command does roughly this for you:

geneos init
geneos install gateway -u ...
geneos add gateway 'Demo Gateway'
geneos install san -u ...
geneos add san localhost -g localhost
geneos install webserver -u ...
geneos add webserver demo
geneos start
geneos ps

Self-Announcing Netprobe

You can install a Self-Announcing Netprobe (SAN) in one line, like this:

geneos init -S -n SAN123 -c /path/to/signingcertkey \
    -g gateway1 -g gateway2 -t Infrastructure -t App1 -t App2 \
    -a ENVIRONMENT=Prod -a LOCATION=London -u [email protected]

This example will create a SAN with the name SAN123 connecting, using TLS, to gateway1 and gateway2, using types and attributes as listed.

Again, you can add authentication options for the downloads using -u and -p.

Another Initial Environment

geneos init -A geneos.lic -u [email protected]

does this (where HOSTNAME is, of course, replaced with the hostname of the server)

geneos init
geneos install gateway -u ...
geneos new gateway HOSTNAME
geneos install san -u ...
geneos new san HOSTNAME -g localhost
geneos install licd -u ...
geneos new licd HOSTNAME
geneos install webserver -u ...
geneos new webserver HOSTNAME
geneos import licd HOSTNAME geneos.lic
geneos start

Instance names are case sensitive and cannot be the same as some reserved words (e.g. gateway, netprobe, probe and more, given below).

You still have to configure the Gateway to connect to the Netprobe, but all three components should now be running. You can check with:

geneos ps

Security and Running as Root

This program has been written in such a way that is should be safe to install SETUID root or run using sudo for almost all cases. The program will refuse to accidentally run an instance as root unless the User config parameter is explicitly set - for example when a Netprobe needs to run as root. As with many complex programs, care should be taken and privileged execution should be used when required.

It is worth reminding users that environment variables do not get passed to programs run with sudo unless you use the -E option (and you are permitted to use it). This is especially important where you have set the download credentials in environment variables. For example, this is likely to fail:

export [email protected]
export ITRS_DOWNLOAD_PASSWORD=supersecret

sudo -u geneos geneos install gateway

While adding the -E flags like this will work:

sudo -E -u geneos geneos install gateway

Environment Settings

The geneos program uses the packages Cobra and Viper to provide the command syntax and configuration management. There is full support for Viper's layered configuration for non-instance settings, which means you can override global and user settings with environment variables prefixed ITRS_, e.g. ITRS_DOWNLOAD_USERNAME overrides download.username

Instance Settings

Each instance has a configuration file. This is the most basic expression of an instance. New instances that you create will have a configuration file named after the component type plus the extension .json. Older instances which you have adopted from older control scripts will have a configuration file with the extension .rc

Historical Configuration Files

Historical (legacy) .rc files have lines, ignoring comments, of form

GatePort=1234

Where the prefix (Gate) also encodes the component type and the suffix (Port) is the setting. Any lines that do not contain the prefix are treated as environment variables and are evaluated and passed to the program on start.

While the geneos program can parse and understand the legacy .rc files above it will never update them, instead migrating them to their modern .json versions either when required or when explicitly told to using the migrate command.

JSON Configuration Files

The .json configuration files share common parameters as well as component type specific settings. For brevity some of these parameters are overloaded and have different meanings depending on the component type they apply to.

While editing the configuration files directly is possible, it is best to use the set and unset commands to ensure the syntax is correct.

Special parameters

All instance types support custom environment variables being set or unset. This is done through the set and unset commands below, alongside the standard configuration parameters for each instance type.

Some component types, namely Gateways and SANs, support other special parameters via other command line flags. See the help text or the full documentation for the set and unset commands for more details.

To set an environment variable use this syntax:

geneos set netprobe example1 -e PATH_TO_SOMETHING=/file/path

If an entry already exists it is overwritten.

To remove an entry, use unset, like this

geneos unset netprobe example1 -e PATH_TO_SOMETHING

You can specify multiple entries by using the flag more than once:

geneos set netprobe example1 -e JAVA_HOME=/path -e ORACLE_HOME=/path2

Finally, if your environment variable value contains spaces then use quotes as appropriate to your shell to prevent those spaces being processed. In bash you can do any of these to achieve the same result:

geneos set netprobe example1 -e MYVAR="a string with spaces"
geneos set netprobe example1 -e "MYVAR=a string with spaces"

You can review the environment for any instance using the show command:

geneos show netprobe example1

Also. output is available from the command command to show what would be run when calling the start command:

geneos command netprobe example1

Component Types

The following component types (and their aliases) are supported:

• gateway - or gateways
• netprobe - or netprobes, probe or probes
• licd - or licds
• webserver - or webservers, webdashboard. dashboards
• san - or sans
• fa2 - or fixanalyser, fix-analyser
• fileagent - or fileagents
• any (which is the default)

The first name, in bold, is also the directory name used for each type. These names are also reserved words and you cannot configure (or consistently manage) components with those names. This means that you cannot have a gateway called gateway or a probe called probe. If you do already have instances with these names then you will have to be careful migrating. See more below.

Each component type is described below along with specific component options.

Type gateway

• Gateway general

• Gateway templates When creating a new Gateway instance a default gateway.setup.xml file is created from the template(s) installed in the gateway/templates directory. By default this file is only created once but can be re-created using the rebuild command with the -F option if required. In turn this can also be protected against by setting the Gateway configuration setting configrebuild to never.

• Gateway variables for templates Gateways support the setting of Include files for use in templated configurations. These are set similarly to the -e parameters:

  geneos gateway set example2 -i  100:/path/to/include

  The setting value is priority:path and path can be a relative or absolute path or a URL. In the case of a URL the source is NOT downloaded but instead the URL is written as-is in the template output.

Type netprobe

• Netprobe general

Type licd

• Licd general

Type webserver

• Webserver general
• Java considerations
• Configuration templates - TBD

Type san

• San general
• San templates
• San variables for templates Like for Gateways, SANs get a default configuration file when they are created. By default this is from the template(s) in san/templates. Unlike for the Gateway these configuration files are rebuilt by the rebuild command by default. This allows the administrator to maintain SANs using only command line tools and avoid having to edit XML directly. Setting configrebuild to never in the instance configuration prevents this rebuild. To aid this, SANs support the following special parameters:
  • Attributes Attributes can be added via set, add or init using the -a flag in the form NAME=VALUE and also removed using unset in the same way but just with a NAME
  • Gateways As for Attributes, the -g flag can specify Gateways to connect to in the form HOSTNAME:PORT
  • Types Types can be specified using -t
  • Variables Variables can be set using -v but there is only support for a limited number of types, specifically those that have values that can be give in plain string format.
• Selecting the underlying Netprobe type (For Fix Analyser 2 below) A San instance will normally be built to use the general purpose Netprobe package. To use an alternative package, such as the Fix Analyser 2 Netprobe, add the instance with the special format name fa2:example[@REMOTE] - this configures the instance to use the fa2 as the underlying package. Any future special purpose Netprobes can also be supported in this way.

Type fa2

• Fix Analyser 2 general

Type fileagent

• File Agent general

Remote Management

The geneos command can transparently manage instances across multiple systems using SSH.

What does this mean?

See if these commands give you a hint:

geneos add host server2 ssh://[email protected]/opt/geneos
geneos add gateway newgateway@server2
geneos start

Command like ls and ps will works transparently and merge all instances together, showing you where they are configured to run.

The format of the SSH URL has been extended to include the Geneos directory and for the add host command is:

ssh://[USER@]HOST[:PORT][/PATH]

If not set, USER defaults to the current username. Similarly PORT defaults to 22. PATH defaults to the local Geneos path. The most basic SSH URL of the form ssh://hostname results in a remote accessed as the current user on the default SSH port and rooted in the same directory as the local set-up. Is the remote directory is empty (dot files are ignored) then the standard file layout is created. If you do not provide any SSH URL then the hostname is taken from the name of the host - e.g.

geneos add host myserver

is taken as:

geneos add host myserver ssh://myserver

How does it work?

There are a number of prerequisites for remote support:

1. Remote hosts must be Linux on amd64
2. Password-less SSH access, either via an ssh-agent or unprotected private keys
3. At this time the only private keys supported are those in your .ssh directory beginning id_ - later updates will allow you to set the name of the key to load, but using an agent is recommended.
4. The remote user must be configured to use a bash shell or similar. See limitations below.

If you can log in to a remote Linux server using ssh user@server and not be prompted for a password or passphrase then you are set to go. It's beyond the scope of this README to explain how to set-up ssh-agent or how to create an unprotected private key file, so please search online.

Limitations

The remote connections over SSH mean there are limitations to the features available on remote servers:

1. Control over instance processes is done via shell commands and little error checking is done, so it is possible to cause damage and/or processes not to to start or stop as expected. Contributions of fixes are welcomed.
2. All actions are taken as the user given in the SSH URL (which should NEVER be root) and so instances that are meant to run as other users cannot be controlled. Files and directories may not be available if the user does not have suitable permissions.

Usage

CAUTION: Please note that the full list of commands and parameters is still changing at this time. This list below is mostly, but not completely, up-to-date.

General Command Flags & Arguments

geneos [FLAG...] COMMAND [FLAG...] [TYPE] [NAME...] [PARAM...]

Where:

• FLAG - Both general and command specific flags
• COMMAND - one of the configured commands
• TYPE - the component type
• NAME - one or more instance names, optionally including the remote server
• PARAM - anything that isn't one of the above

In general, with the exception of TYPE, all parameters can be in any order as they are filtered into their types for most commands. Some commands require arguments in an exact order. For example, these should be treated the same way:

geneos ls -c gateway one two three geneos ls gateway one -c two three

Reserved instance names are case-insensitive. So, for example, "gateway", "Gateway" and "GATEWAY" are all reserved.

The NAME is of the format INSTANCE@REMOTE where either is optional. In general commands will wildcard the part not provided. There are special REMOTE names @localhost and @all - the former is, as the name suggests, the local server and @all is the same as not providing a remote name.

There is a special format for adding SANs in the form TYPE:NAME@REMOTE where TYPE can be used to select the underlying Netprobe type. This format is still accepted for all other commands but the TYPE is silently ignored.

File and URLs

In general all source file references support URLs, e.g. importing certificate and keys, license files, etc.

The primary exception is for Gateway include files used in templated configurations. If these are given as URLs then they are used in the configuration as URLs.

Global Commands

• geneos version Show the current version of the geneos program, which should match the tag of the overall geneos package.

• geneos help General help, initially a list of all the supported commands.

• geneos completion

Instance Details

• geneos ls [TYPE] [NAME...] Output a list of all configured instances. If a TYPE and/or NAME(s) are supplied then list those that match.

• geneos ps [TYPE] [NAME...] Show details of running instances.

• geneos logs [-f | -n N | ...] [TYPE] [NAME...] Show log(s) for matching instances. Flags allow for follow etc.

Environment Commands

• geneos init [FLAGS] [USERNAME] [PATH] [PARAMS] The FLAGS are:

  • -A LICENSE Initialise and start an all environment Initialise the environment. This command creates a directory hierarchy and optionally installs Geneos software packages and also optionally creates instances and starts them.
  • -D Initialise and start a demo environment
  • -S Initialise and start a San. See the -n option below. Takes all the same PARAMS as for adding a San to specify template settings.
  • -C Create a root and signing certificate and use these for all new instances
  • -l Follow logs after starting any created instances (for -A, -D and -S above)
  • -F Force initialisation, ignore existing files and directories in destination
  • -n NAME Use the NAME for instances instead of the default hostname. This is especially useful for Sans and Gateways as the templates use this name to fill in various configuration item defaults
  • -c CERT and/or -k KEY Import certificates and keys during initialisation. See geneos tls import for more details. When a valid signing certificate and key are imported then all subsequent new instances will have individual certificates and keys created.
  • -T Rebuild the default templates using the embedded files. This is primarily to update templates when new versions of this program are release or if they have become corrupted
  • -N Download from nexus.itrsgroup.com for testing. Only available to ITRS staff.
  • -p Use the Nexus snapshots repository instead of the default releases when using -N above
  • -V Version filter for downloads. Defaults to the latest version found.
  • -w FILE A Gateway template file to use instead of the embedded one
  • -s FILE A San template file to use instead of the embedded one
  • -e, -i, -g, -a, -t, -v These options set environment, include, gateway. attribute, type and variable values and can be specified multiple times. The values are used as inputs to templates for Gateway and SAN instances.
  • Only one of the -T, -S, -D or -A options are valid and only the -T option can be used for multiple calls to this command unless -F is also used.

• geneos tls ... TLS operations. See below.

• geneos show [global|user] Show the running configuration or, if global or user is supplied then the respective on-disk configuration files. Passwords are simplistically redacted. The instance specific show command is described below.

• geneos set [global|user] KEY=VALUE... Set a program-wide configuration option. The default is to update the user configuration file. If global is given then the user has to have appropriate privileges to write to the global config file (/etc/geneos/geneos.json). Multiple KEY=VALUE pairs can be given but only fields that are recognised are updated.

• geneos home [TYPE] [NAME] The home command outputs the home directory of the first matching instance, or Geneos if there is no match or no options passed to the command. This is useful for automation and shortcuts, w.g. in bash:

  $ cd $(geneos home netprobe example1)

Please note that if geneos home returns an empty string because of an error the cd command will take you to your home directory.

Package Management Commands

• geneos install [FLAGS] [TYPE] [latest|VERSION|FILE|URL...] Download and install a release archive in the packages directory. If a symbolic link for the desired base version already exists it is not updated unless the -U flag is given. The FLAGS are:

  • -b BASENAME The base name of the installation symbolic link. Defaults to active_prod
  • -l Local archives only
  • -n No save of downloaded archives
  • -H HOST Install only on remote HOST. HOST must be configured
  • -N Use nexus.itrsgroup.com for downloads. Only available to ITRS staff
  • -p Use the snapshots repository and not the default releases with -N above
  • -V Version filter, installs latest matching version. Defaults to latest available version.
  • -U Update base name link to installed version
  • -T TYPE:VERSION Override the component type and version numbers to allow installation from files with generic names, for example gateway.tgz

• geneos update [TYPE] [VERSION] Update the component base binary symlink

Control Commands

• geneos start [-l] [TYPE] [NAME...] Start a Geneos component. If no name is supplied or the special name all is given then all the matching Geneos components are started.

• geneos stop [-K] [TYPE] [NAME...] Like above, but stops the component(s) -K terminates forcefully - i.e. a SIGKILL is immediately sent

• geneos restart [-l] [TYPE] [NAME...] Restarts matching geneos components. Each component is stopped and started in sequence. If all components should be down before starting up again then use a combination of start and stop from above.

• geneos reload [TYPE] NAME [NAME...] Signal the component to reload it's configuration or restart as appropriate.

• geneos disable [TYPE] [NAME...] Stop and disable the selected components by placing a file in the working directory with a .disable extension

• geneos enable [TYPE] [NAME...] Remove the .disable lock file and start the selected components

• geneos clean [-F] [TYPE] [names] Clean up component directory. Optionally 'full' clean, with an instance restart.

Configuration Commands

• geneos add [TYPE] NAME [NAME...] Add a new Geneos component configuration.

• geneos migrate [TYPE] [NAME...] Migrate legacy .rc files to .json and backup the original file with an .orig extension. This backup file can be used by the revert command, below, to restore the original .rc file(s)

• geneos revert [TYPE] [NAME...] Revert to the original configuration files, deleting the .json files. Note that the .rc files are never changed and any configuration changes to the .json configuration will not be retained.

• geneos rebuild [-n] [-F] [TYPE] [NAME...] Rebuild instance configuration, typically used for Self-Announcing Netprobes. By default it restarts any instances where the configuration has changed. Flags are:

  • -n Do not restart instances
  • -f Force rebuild for those instances that are marked initial only.

• geneos command [TYPE] [NAME...] Shows details of the full command used for the component and any extra environment variables found in the configuration.

• geneos move [TYPE] source destination

• geneos copy [TYPE] source destination These commands either move or copy instance(s). If the source and destination are on the same location/remote then move acts as a rename. If a destination is given as a bare remote, e.g. @remotename then the source instance name is kept. If both source and destination are remotes then all matching instances are moved or copied. If no TYPE is given then all matching instances will be acted on. If the destination is a different location/remote then the port number of the instance(s) may be updated to avoid clashing with existing instances. Because all changes require the writing of a new instance configuration file, all instances are migrated to new JSON configuration files if required.

• geneos delete [-F] component name Deletes the disabled component given. Only works on components that have been disabled beforehand, unless the -F (force) flag is supplied.

• geneos import [-c common] [-r host] [TYPE] [NAME] [file|url|-]... Import a file into an instance working directory, from local file, url or stdin and backup previous file. The file can also specify the destination name and sub-directory, which will be created if it does not exist. Examples of valid files are:

  geneos import gateway Example gateway.setup.xml
  geneos import gateway Example https://server/files/gateway.setup.xml
  geneos import gateway Example gateway.setup.xml=mygateway.setup.xml
  geneos import gateway Example scripts/newscript.sh=myscript.sh
  geneos import gateway Example scripts/=myscript.sh
  cat someoutput | geneos import gateway Example config.json=-

Like other commands that write to the file system is can safely be run as root as the destination directory and file will be changed to be owned by either the instance or the default user, with the caveat that any intermediate directories above the destination sub-directory (e.g. the first two in my/long/path) will be owned by root.

TLS Operations

The geneos tls command provides a number of subcommands to create and manage certificates and instance configurations for encrypted connections.

Once enabled then all new instances will also have certificates created and configuration set to use secure (encrypted) connections where possible.

The root and signing certificates are only kept on the local server and the tls sync command can be used to copy a chain.pem file to remote servers. Keys are never copied to remote servers by any built-in commands.

• geneos tls init Initialised the TLS environment by creating a tls directory in Geneos and populating it with a new root and intermediate (signing) certificate and keys as well as a chain.pem which includes both CA certificates. The keys are only readable by the user running the command. Also does a sync if remotes are configured.

  Any existing instances have certificates created and their configurations updated to reference them. This means that any legacy .rc configurations will be migrated to .json files.

• geneos tls import FILE [FILE...] Import certificates and keys as specified to the tls directory as root or signing certificates and keys. If both certificate and key are in the same file then they are split into a certificate and key and the key file is permissioned so that it is only accessible to the user running the command. Root certificates are identified by the Subject being the same as the Issuer, everything else is treated as a signing key. If multiple certificates of the same type are imported then only the last one is saved. Keys are checked against certificates using the Public Key part of both and only complete pairs are saved.

• geneos tls new [TYPE] [NAME...] Create a new certificate for matching instances, signed using the signing certificate and key. This will NOT overwrite an existing certificate and will re-use the private key if it exists. The default validity period is one year. This cannot currently be changed.

• geneos tls renew [TYPE] [NAME...] Renew a certificate for matching instances. This will overwrite an existing certificate regardless of it's current status of validity period. Any existing private key will be re-used. renew can be used after import to create certificates for all instances, but if you already have specific instance certificates in place you should use new above. As for new the validity period is a year and cannot be changed at this time.

• geneos tls ls [-a] [-c|-j] [-i] [-l] [TYPE] [NAME...] List instance certificate information. Flags are similar as for the main ls command but the data shown is specific to certificates. Additional flags are:

  • -a List all certificates. By default the root and signing certificates are not shown
  • -l Long list format, which includes the Subject and Signature. This signature can be used directly in the Geneos Authentication entry for users for non-user authentication using client certificates, e.g. Gateway Sharing and Web Server.

• geneos tls sync Copies chain.pem to all remotes

Configuration Files

General Configuration

• /etc/geneos/geneos.json - Global options
• ${HOME}/.config/geneos.json - User options
• Environment variables ITRS_option

General options are loaded from the global config file first, then the user one and any environment variables override both files. The current options are:

• geneos The home directory for all other commands. See Directory Layout below. If set the environment variable ITRS_HOME overrides any settings in the files. This is to maintain backward compatibility with older tools. The default, if not set anywhere else, is the home directory of the user running the command or, if running as root, the home directory of the geneos or itrs users (in that order). (To be fully implemented) This value is also set by the environment variables ITRS_HOME or ITRS_GENEOS

• download.url The base URL for downloads for automating installations. Not yet used. If files are locally downloaded then this can either be a file:// style URL or a directory path.

• download.username download.password These specify the username and password to use when downloading packages. They can also be set as the environment variables:

  • ITRS_DOWNLOAD_USERNAME
  • ITRS_DOWNLOAD_PASSWORD

• defaultuser Principally used when running with elevated privilege (setuid or sudo) and a suitable username is not defined in instance configurations or for file ownership of shared directories.

• GatewayPortRange & NetprobePortRange & LicdPortRange ...

Component Configuration

For compatibility with earlier tools, the per-component configurations are loaded from .rc files in the working directory of each component. The configuration names are also based on the original names, hence they can be obscure. the migrate command allows for the conversion of the .rc file to a JSON format one, the original .rc file being renamed to end .rc.orig and allowing the revert command to restore the original (without subsequent changes).

If you want to change settings you should first migrate the configuration and then use set to make changes.

Note that execution mode (e.g. GateMode) is not supported and all components run in the background.

Directory Layout

The geneos configuration setting or the environment variable ITRS_HOME points to the base directory for all subsequent operations. The layout follows that of the original gatewayctl etc. including:

packages/
  gateway/
    [versions]/
    active_prod -> [chosen version]
  netprobe/
  licd/
gateway/
netprobe/
licd/

The bin/ directory and the default .rc files are ignored so be aware if you have customised anything in bin/.

As a very quick recap, each component directory will have a subdirectory with the plural of the name (e.g. gateway/gateways) which will contain subdirectories, one per instance, and these act as the configuration and working directories for the individual processes. Taking an example gateway called Gateway1 the path will be:

${ITRS_HOME}/gateway/gateways/Gateway1

This directory will be the working directory of the process and also contain an .rc configuration file as well as a .txt file to capture the STDOUT and STDERR of the process, like this:

gateway.rc
gateway.txt

There will also be an XML setup file and so on.
